Open Powerpoint Presentation Downloaded from internet

[ajstan]

Hi,

 

I'm having problems with a number of users who want to download PPT 2010 presentations from Fronter (or anywhere on the internet for that matter).

 

They click to download the file, it downloads perfectly but when they try and open it they receive this error:

 

 

and the file refuses to open even if you press 'repair'. Confusingly it works for most users without any problems.

 

The only way to get around this is to open the PPT presentation properties and press 'unblock' and it works

 

 

Although this is possible for the teachers, the students have right click disabled and it's an impractical solution anyway.

 

Does anybody know if this is something that can be fixed with a GPO?

 

Thanks

Alex

It'll be in the Trust Center settings for the powerpoint GPO.
